Your roof: Geneva
For an apartment building or condominium, clarify roof rights, owner consent and access. Include cable routes, protection and maintenance in the same plan.
In all cases, the useful surface area is almost always less than the gross surface area announced. Skylights, chimneys, setbacks, shading and future maintenance needs must be integrated before talking about final power.
Specify access, lifting equipment and protection of the work area. Include the constraints identified during the survey in the quotation.
Exposure and access: Geneva
Request a survey of nearby shading and the horizon, with monthly generation estimates. Compare options for your building using the same weather data and loss assumptions.
Show chimneys, roof windows and other obstacles on the installation layout. Value surplus using the confirmed export contract, with guarantees of origin accounted for separately.
Full cost and grants: Geneva
The displayed scenario uses an indicative installed cost for 8 kWp. A quote must specify equipment, roofing and electrical work, connection, inspections and fees before deducting confirmed grants.
Programmes depend on the municipality and available funds. Obtain written confirmation of amounts, timing, limits and combined support for your address before including them in the budget.
Define included and excluded work during the technical survey. Agree on tests, inspections and documents to be provided at handover.
Output must be assessed for the actual roof, its orientation, shading and condition. Tariffs depend on the grid, product and contract; a cantonal average does not replace your bill.
Building procedures: Geneva
Use the building’s hourly consumption to size the project. Specify fall protection and access for installation and maintenance.
A serious estimate specifies who prepares the announcement, who manages the connection, who follows the administrative back and forth and how any comments are absorbed into the planning.
In Geneva, check Pronovo, the SIG 2026 solar premium and municipal aid before signing. If the timeline is poorly managed, you lose time and sometimes value on helpers.
Measure usable roof area with obstacles and required clearances included. Distinguish avoided purchase costs from the tariff paid for exported surplus.
